[ Upstream commit 3f3752705dbd50b66b66ad7b4d54fe33d2f746ed ]

This patch fixes an issue in drivers/hid/hid-input.c where USB HID control null state flag is not checked upon rejecting inputs outside logical minimum-maximum range. The check should be made according to USB HID specification 1.11, section 6.2.2.5, p.31. The fix will resolve issues with some game controllers, such as:
